ЭФФЕКТИВНОСТЬ ПРИМЕНЕНИЯ ОСТЕОПЛАСТИЧЕСКОГО МАТЕРИАЛА «СТИМУЛ-ОСС» В СОЧЕТАНИИ С ОБОГАЩЁННОЙ ТРОМБОЦИТАМИ АУТОПЛАЗМОЙ ПРИ УДАЛЕНИИ ДИСТОПИРОВАННЫХ И РЕТИНИРОВАННЫХ НИЖНИХ ТРЕТЬИХ МОЛЯРОВ

Abstract

Objective: Optimization tactics and treatment results of the difficult eruption of lower third molars on the bases of the osteoinductive materials.Methods: Depending on the chosen tactics of treatment, patients were divided into 2 groups. The first (main) group (29 patients – 51%), in which, after extraction of the lower third molar, the bone defect filled by the osteoplastic material «Stimul-OSS», and then covered by membrane-shaped platelet-rich plasma. And second (control) group (28 patients – 49%), where treatment was carried out according to traditional techniques.Results: When analyzing the dynamics of leukocyte infiltration index by 7 days of treatment, the level of leukocytes in group II decreased to 6.0±0.3×109 /l, the ESR was 9.08±4.6 mm/h, whereas in the main group during this time, the leukocyte and ESR values were 5.60±0.3×109 /l and 9.09±2.89 mm/h, which indicated the normalization of the general condition of the patients. The results of densitometry in the main group in 12 months after tooth extraction corresponding to the norm – 1631.8±14.9 units. Analysis of the acidic-alkaline state of the alveolar socket of the removed tooth in the observation dynamics showed that a more positive picture noted in the main group. Conclusion: The developed method of bone plastic surgery by the surgical treatment of retained dystopic lower third molars with the application of combination of osteoplastic material «Stimul-OSS» with platelet-rich plasma is pathogenetically grounded. This technique reduces healing time and treatment; has a medico-social and economic effectiveness of reduction of hospital stay and improved patients quality of life.Keywords: Retention, dystopia, platelet-rich plasma, Stimul-OSS, osteoplastic materials.
